MANTLE-SUPPORT.

SPECIFICATION forming part Of Letters Patent NO. 683,648, dated October 1, 1901. Application filed January 4, 1901. Serial No. 42,044. (No model-J T0 all whom, it may concern:

Be it known that 1, JAMES IRONS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Mantle-Supports, of which the following is a specification.

My invention relates particularly to an improvement in detachable mantle-supports for incandescent mantles; and my object is to provide a simple construction wherein provision is made against the mantle-standard leaning, sagging, or getting out of order.

My invention is illustrated in its preferred form in the accompanying drawings, in

Figure 1 represents an elevational view of the device, showing the manner in which the mantle is supported; Fig. 2, a perspective view of the mantle-standard detached from the gauze cap, and Fig. 3 ahorizontal section taken as indicated at line 3 of Fig. 1.

A represents the gauze cap, B a mautle,and G the mant1e-support. The gauze cap here shown is formed separately from the burner to which it is in use applied; but it will be understood that the invention is applicable to use in connection with gauze caps formed integrally with the burners. The gauze cap is provided with a raised thread a. The mantle-standard is provided at its base with a helical coil or partial coil b, which engages the thread a. By preference the mantlestandard is formed from a single piece of wire and has vertical sides I) b and a connecting top part or web h The side I) has at its base the thread or spiral b, and the side b has at its base an inturned offset 19 The gauze cap is sometimes formed with recesses 12 c and in the present construction should be provided with a stop 0 for engaging the offset 1)". By preference the stop 0 is formed from the material punched from the recess 0'. Preferably, also, the stop should be curved to en= gage the offset b, so as to prevent its retraction.

It will be understood that the manner of connecting the standard with the gauze cap is to screw the former down until the offset 19 enters the recess provided for it at the stop 0 the springiness of the stop serving to prevent accidental retraction.

It is usual to transport mantles ready mounted upon their standards and gauze caps, the whole being inclosed within a cylindrical casing. The two sides or uprights 0f the standard serve effectually to keep the mantle-standard centered in its case and also serve when the mantle is in use to prevent the standard from inclining or sagging.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a gauze cap of a mantle-standard provided with two upright members connected at their tops, one of said members having at its base screw connection with the'gauze cap, and the lower end of the other upright member serving to engage a stop on the gauze cap; substantially as de' scribed. v

2. The combination of a gauze cap provided with a screw-thread and a stop, and a mantle standard comprising two upright members connected at their tops and receiving between them the mantle, one of said upright members having a spiral at its base for engaging the thread on the gauze cap, and the other of said upright members having at its base an otfset engaging said stop, substantially as described.

3. The combination of a gauze cap provided with a screw-thread and with a curved stop bent to afford a spring, and a mantle-standard comprising two upright members connected at their tops, one of said members having at its base a spiral for engaging said thread and the lower end of the other of said members serving to pass into locking engagement with said stop, substantially as described.

4. The combination of a gauze cap having a thread and an integrally-formed mantlestandard having two upright members, a top connecting member and a spiral at the base of one upright member engaging said thread, the base of the other upright member affording a stop, substantially as described.
